摘要
介绍一种以显微镜结构为基础的浸没式阵列激光扫描直写光刻系统的光路结构、有效焦深、自动调焦及曝光能量控制的原理和方法。实验系统的有效数值孔径(ENA)为1.83,使用的激光波长为355nm时,在实验室条件下得到的最细线条宽度为65nm。
The principles and methods of the optical system, efficiency focus depth, auto focusing, exposure energy con（rol of a laser array direct scanning microlithography system with immersion lens are described in this paper. The efficiency numerical aperture is 1.83. The minimal line width is 65nm with 355nm laser beam scanning photolithography in laboratory.
